So as long as you tell QEMU to emulate a CPU model for arm7 that can do hard float, then QEMU can support guests OS which use hard or soft float. This is a long winded way of saying that in terms of representing architectures in libvirt and libosinfo, we don't need a distinction between hard & soft float arm. They're all just arm7. The distinction is more akin having an i686 guest, which is compiled to assume a CPU model with SSE instructions. This is a concept we don't track in libosinfo right now. We could, but I'd just ignore until its critical (if ever).
